MAF Heat Shield

[MPO]

I'm looking for a heat shield (jacket type) to go around my Lucas 20am.

I have seen them on Pistonheads Classifieds in the past.

Anyone know where I can get one nowadays?

Cheers

Thats the one!

Thanks

Why not get a heat she'd to prevent radiant heat getting to the MAF, that so called jacket will also insulate it when it's got hot

Fair point, what shields are you thinking of? Exhaust?

My 20am electronics are horizontal (on the top) compared to the vertical 5am but it still gets pretty hot.

This solution is pretty effective

I have one you can have for £10 plus P&P as I don't run a MAF now.

That does look good, loving your engine bay and the exhaust setup

I doubt that is the case for the MAF. The constant flow of induction air will keep the temperature low inside the blanket

I made my MAF blanket from this stuff folded over on itself to seal the edges

Nice one Bob!

I may try this on my induction pipe and a few cable ties - cheap enough!

Hmmm that engine bay is missing a rotrex and you know i

That could well be the case, but in slow moving traffic on a hot day, a jacket will insulte the heat in

Okay, let's look at the facts. Insulation slows the propagation of temperature across itself. The inside of the MAF is cold and the outside is subject to varying amounts of radiant heat. If you use a thermal barrier then heat will not easily cross the barrier but even minimal internal cooling by air flow will act quickly.

Think about it, if it did get hot inside the MAF due to high temperature in the engine bay then it must be the same temperature or lower inside the MAF due to induction air flow. Not having the thermal barrier would mean the MAF would become hotter quicker and the cooling by induction air would have less effective. It can't cool down if the engine bay is hotter than the MAF and the engine bay must be hotter than the MAF because that's what is heating it

What you say would be correct if nothing was cooling the inside. It is better to protect the MAF from heat radiation and more so because the delicate electronics are on the siide that is subject to thermal radiation. Having no protection ensures that the electronics are subjected to the maximum radiation especially in slow traffic

I don't disagree with you, I just believe a protective shield from radiant heat is an effective solution without insulating heat in.

If it can help i used a t6 turbo jacket and it fit my maf like a charm... i just get the cheapest turbo conversion only lack a few hps...

Just to throw another option out there, which I've done and works fine. Is relocate it to just after the air filter in the nose and extend the wiring harness.

I do Bob you are also preventing the electronic internal components from getting cooked these will not be protected by the cool air rushing thru the MAFS Andav's solution is a far better solution long term its cheap and effective

Mine has a heat shield as mentioned above, the temperature in that area is not very hot though, it's warm but you could easily handle the MAF after a long run.
